A frame handling system and frame handling method therefor which is capable of speedily handling the frames appropriately according to the type of lines, requiring a minimum function/circuit involvement. this invention is composed of a cell segmentation and reassembler (SAR) portion and a frame handling portion, wherein SAR portion receives a stream of ATM cells from lines VC1 to VCn, separates ATM cells depending on whether they come from VP or VC connections, and assembles them into AAL5 frames. While AAL5 frames being formed, the subsequent frame handling portion seeks the information regarding handling for each frame which has been received through VP or VC connection. The assembled frame containing the data for handling is delivered to the frame handling portion. Thus, it is possible for the frame handling portion to dynamically handle frames depending on the data for frame handling provided by SAR portion.
